Question 120 (part 2) · LDEK · Dentin hypersensitivity
Choose true statements:
1) in visual assessment, hypersensitive dentin does not differ from insensitive, it differs however with the intensity of harmless external stimulus;
2) post-treatment dentin sensitivity is caused by polymerization shrinkage;
3) hypersensitivity of lateral teeth dentin restored with composite material is usually caused by occlusal overloading or marginal microleakage;
4) dentin hypersensitivity after bleaching vital teeth is caused by forming diffusion canals reaching dentin and increased enamel porosity;
5) tooth pain post crown cementing, especially with glass-ionomer cements, is caused by polymerization shrinkage of material used for cementing.
